Application filed April 14, 1892- Serial No. 429,227. (No model.) Patented in France February 20, 1890, No. 203,819: in Belgium August 22, 1890, N0. 91,732; in England August 25, 1890, No. 13,349; in Italy September 11, 1890, No. 145; in Spain April 6, 1891, No. 11,772, and in Austria-Hungary December 15, 1891,No. 38,664 and No. 63,358.

To all whom it may concern..-

Be it known that 1, APosToLos MAEANeos, a citizen of the Republic of France, residing at Marseilles, France, have invented an Improved Grain-Elevator, of which the following is a specification.

The invention has been patented in France, No. 203,819, dated February 20, 1890; in Belgium, No. 91,732, dated August 22, 1890; in Great Britain, No. 13,349, dated August 25, 1890; in Italy, No. 145, dated September l1, 1890; in Austria-l-Iungary, No. 38,664 and No. 63,358,6latedDecember15, 1891, and in Spain, No. 11,772, dated April 6, 1891.

My invention relates to an apparatus for vertically raising grain and pulverized material, and is especially designed for use in loading and unloading ships, for the delivery of grain to storage-elevators, and in handling the material stated on docks and in storagehouses generally.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of sufficient of a grain apparatus as is necessary to show my invention, the raised position of the vertical conveyer-tube, with its chute, being shown in dotted lines. Fig` 2 is a front view of the same, with a part of the frame broken away. Fig. 3 is a plan view of the same. Figs. 4 and 5 are detail longitudinal and transverse sections of the inclosing case and conveyer. Fig. 4a is a view of the sections of the screw conveyer partly in section. Fig. 6 is a horizontal sectional plan View taken in the plane of the lateral discharge-conveyer. Figs. 7 and 8 are a detail side and vertical sectional view, respectively, of the lower part of the conveyer-tube and conveyer.

AS illustrated, my improved apparatus will be generally distinguished, involving the following features: irst, of the elevator, which raises the material from the hold of the vessel; second, of a laterally extending discharge-conveyer, which delivers the material at the desired place; third, of the frame for supporting the elevator, and, fourth, of the actuating devices.

The elevator proper is composed of a series of juxtaposed elements connected together as hereinafterdescribed. Each one of these said elements comprises a tubular section containing a section of spiral conveyer which moves with but slight friction. These sections are all alike, with the exception of the iirstand lowermost one, which constitutes the feeder. This said lowermost section consists of a tube 1, (see Figs. 7 and 8,) open at its lower end, at which point it is provided with a yoke-bracket a a, provided centrally with a bearing-step b in a line with the spiral conveyer and adapted to receive the end of the axis 2in the same.

By referring to Fig. 8 it will be seen that the pitch of the blade of the spiral conveyer beneath the end edge of the section 1 would form a contracted portion in which sections of metal, nails, Wire, and other foreign matter might become jammed and seriously interfere with the easy movement of the apparatus. To provide against this, I provide the axisot the spiral conveyer' adjacent to the lower edge of section 1 with a block 3. A spring projection d, located on one side of the bracket adjacent to the lower edge of the section 1, is adapted to intercept strings, cord, and other like elements in the material. The tubular sections of the conveyer proper are provided at their adjacent ends with lateral iianges o, which are correspondingly notched, as indicated at 30, Figs. 4 and 5, so that hinged bolts 31, secured on one of the sections, may be swung to bear within each pair of notches and clamp the iianges rigidly together through the medium of the nuts 4. These clamping portions conjointly form a recess to receive the abutting ring portions 2 and 2 on the end of each spiral conveyer-section, the adjacent faces being gear-dresscd, so that the two rings will mesh with each other and communicate the motion of one section to the other. Such an arrangement enables the strain to be taken off the central spindle, which is also sectional in its character, having socket-and-pin connections 1l between them, as shown in Fig. 41. The Webs 3ad illustrate how the conveyer-blades are connected to the rings. The upper tubular sections F F of the elevator proper have their lateral flanges c so disposed that a clamp-section E', held by hand-screw K, serves to hold said sections rigidly in position. N ow by opening the upper E and slightly loosening the lower E the latter will serve as a guide to permit the descent of all of the sections, except the top one, thus admitting of the introduction of an additional section within the conveyer to lengthen the same. The section which is to be held is supported by its lateral flange resting upon the clamp-ring E. These clamp-rings are pivoted to the cross-braces 32, extending between and secured to the depending pivoted hanger-arms D, said braces t having central openings through which the conveyer-tubes pass.

The top section F is provided with a discharge-spout u, adapted to deliver the material elevated into a hopper T, supplying the material to a lateral tube M, containing a spiral conveyer-shaft S, made up of sections, 'as previously described,with reference to the main conveyer. Bracket-arms extend integrally from the casing and pivot-ally engage a shaft m to admit of the vertical adjustment of the lateral conveyer M in an arc of the circle. The relation of the bevel-gearin g R R is such that the lower belt-wheel Q when operated through its belt 4l and upper beltwheel Q can actuate the conveyer-shaft S, notwithstanding the pivotal position of the lateral conveyer. The shaft b of the main conveyer is driven through the medium of the bevel gear-wheels P P, pinion 0, larger gear-wheel O, upper gear-wheel Q', and exterior gear-wheel N.Y i. ,i

The winch I is operated by a hand-crank to wind or feed a cable secured to an ear or bracket on the main conveyer to elevate or lower the same. The connection from the hand-crank l to the winch is made through the sprocket-pinion 33, the chain or belt 34, the belt-wheel 36, its shaft 37, pinion 38, and gear 39. The cables 39X pass from the winch up over the sheaves 40, journaled in the main frame, and thence down to the cross-bar H, connected to the upper section F of the conveyer, the said bar moving on ways formed on the hanger-arms D, Fig. 2. The elevated position of the conveyer is shown in dotted lines, Fig. l.

The upper part G of the framework supporting the main conveyer is mounted in the t side standards A of the main frame through the medium of trunnions and enables the inner frame, including the bars D D, to swing the main conveyer when 1t is desirable, either VY for thepurpose of adjusting the position of the same or to provide against longitudinal rolling or pitching of the boat. By having the base-rails B engaging the longitudinal guide-rails L the longitudinal movement before referred to is assisted.

The material may be fed to the lower end of the main conveyer by any suitable means or supplemental conveyer or the material may be shoveled to the main conveyer by attendants providedV for the purpose. The hangers form a supplemental frame, on which is located the Vbearing for the upper end of the conveyershaft. The transverse shaft, which communicates motion to the conveyershaft, extends through the pivotal bearing of the hanger.
